Description

Technical Field

[0001] This application relates to the field of superconducting magnet installation technology, and more particularly to a superconducting magnet assembly trolley. Background Technology

[0002] Superconducting accelerator modules are the core units of large-scale particle accelerators, typically containing a complete superconducting magnet composed of two superconducting magnet half-rings joined together. These magnet half-rings are characterized by their large weight, precise structure, and extremely high requirements for the accuracy of their mating surfaces. Current technology requires separating the superconducting magnet in half, transferring each pair of half-rings to the desired installation location, aligning them, joining them together, and finally installing them onto the vacuum pipe flange of the accelerator module. This process presents the following main technical challenges: Superconducting magnets are heavy and require a stable platform for support and separation. Traditionally, the process of assembling superconducting magnets involves manual assembly using a crane and a simple support frame. This process not only poses safety risks but is also extremely difficult in terms of adjusting the semi-annular orientation and achieving micron-level precision alignment in the radial and axial directions. It heavily relies on the operator's experience and feel, resulting in low efficiency and unreliable accuracy. Furthermore, the assembling process is unstable and prone to stress and damage. Summary of the Invention

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a superconducting magnet assembly trolley to ensure the safety, accuracy and efficiency of superconducting magnets during separation, assembly, alignment and transportation, and to achieve fully controllable, efficient and high-precision operation of superconducting magnet semi-ring docking.

[0004] This application provides the following technical solution: This application provides a superconducting magnet assembly cart, comprising: A support component, wherein the support component is movable; A magnet support assembly is disposed on a support assembly. The magnet support assembly includes a first locking member and a pair of carrier members. The pair of carrier members are respectively used to connect a pair of superconducting magnet semi-rings of a detachable superconducting magnet. Each carrier member can move relative to the support assembly, separating or moving closer to each other, so that the superconducting magnet can be separated into a pair of superconducting magnet semi-rings or brought together. When the superconducting magnet is separated, the connection between the first locking member and the carrier members is released, and the carrier members are separated by a driving member, thereby separating the superconducting magnet into a pair of superconducting magnet semi-rings. After the pair of superconducting magnet semi-rings are brought together, the first locking member is connected to each of the carrier members to lock the position of each carrier member, and the connection between at least one carrier member and the first locking member is detachable.

[0005] In some embodiments, the carrier component includes: A reference element having a reference surface, wherein each of the carrier elements is mounted on the reference surface in a manner that allows them to be close to or far from each other.

[0006] In some embodiments, the carrier component further includes: A first adjusting member is connected to the reference member. The first adjusting member is used to adjust the deflection of the reference member so that the flange of the superconducting magnet is parallel and fitted to the flange of the vacuum tube after the two parts are closed.

[0007] In some embodiments, the carrier component includes: At least two support frames are connected in sequence to form an installation platform, and the connection between at least one adjacent support frame is detachable. The first adjusting member is disposed on the installation platform. At least two movable parts, each of the carriers being provided with at least one of the movable parts, so that each of the carriers can move independently when the detachable connection is disengaged; and / or, so that the installation platform can move as a whole.

[0008] In some embodiments, the carrier component further includes: At least two second adjusting members are provided, and each of the support frames is provided with at least one second adjusting member. Each second adjusting member can adjust the height of the corresponding support frame and can also adjust the levelness of the reference surface.

[0009] In some embodiments, there are multiple first adjusting members, and each of the support frames is provided with at least one first adjusting member. Each first adjusting member includes a pair of clamping portions, and a clamping area for accommodating the reference member is formed between the pair of clamping portions. The pair of clamping portions are arranged in a manner that allows them to move closer to or further away from each other, so that each clamping portion can abut and limit the corresponding side of the reference member. By adjusting the position of the clamping portion of each first adjusting member, the reference member is driven to deflect, and the deflection direction of the reference member is parallel to the reference surface.

[0010] In some embodiments, the reference member includes a plurality of connecting segments, each of the support frames is provided with a connecting segment, and in adjacent connecting segments, one of the connecting segments includes a plug-in portion and the other connecting segment includes a plug-in mating portion, wherein the plug-in portion and the plug-in mating portion are plugged in and positioned together.

[0011] In some embodiments, the second adjusting member is a lifting support leg, which includes a fixed end and a telescopic end. The fixed end is disposed on the support frame, and the telescopic end can extend or retract relative to the fixed end to abut or detach from the ground.

[0012] In some embodiments, the carrier includes a support base, a lower top, and a side top. The support base is detachably connected to the lugs of the superconducting magnet half-ring. The side top and the lower top are both disposed on the support base. The side top is used to abut against and support the side of the superconducting magnet half-ring, and the lower top is used to abut against and support the bottom of the superconducting magnet half-ring.

[0013] In some embodiments, the magnet support assembly further includes two drive members, each of the carrier components being connected to one of the drive members, and each drive member being used to drive the corresponding carrier component to move.

[0014] The embodiments of this application have the following advantages: This application provides a superconducting magnet assembly trolley where each carrier component can be controllably moved relative to the supporting assembly. This allows two superconducting magnet half-rings to smoothly and precisely approach and separate from each other, achieving micron-level alignment adjustment in both radial and axial directions. This significantly reduces reliance on human experience and feel, ensuring the precision of the mating surfaces and meeting the requirements for precision assembly of superconducting magnets. Simultaneously, during separation, separation stress is reduced, protecting the superconducting magnet half-rings. A first locking element locks the position of the carrier components after they are joined, ensuring the stability of the mating state. At least one carrier component is detachably connected to the first locking element, facilitating subsequent adjustments or disassembly. This achieves integrated, mechanized operation throughout the entire process from joining and alignment to transport, greatly improving assembly efficiency and process controllability. Furthermore, the detachable connection between the carrier component and the superconducting magnet half-ring facilitates the clamping and replacement of the half-ring. The mobility of the supporting assembly further expands the trolley's application scenarios within the assembly workshop, supporting the transport and positioning of the half-rings between workstations, adapting to the needs of continuous multi-process operations, especially in conjunction with positioning vacuum tube flanges. Furthermore, it reduces reliance on highly skilled operators, lowers labor intensity, and facilitates standardized, highly repetitive, and high-quality assembly operations.

[0024] In related technologies, superconducting accelerator modules are the core units of large-scale particle accelerators, typically containing a complete superconducting magnet composed of two superconducting magnet half-rings joined together. These magnet half-rings are characterized by their large weight, precise structure, and extremely high precision requirements for mating surfaces. Current superconducting magnet installation technology involves first smoothly separating a pair of superconducting magnet half-rings from the complete superconducting magnet, then assembling, aligning, and finally installing the half-rings into the vacuum pipe of the accelerator module. This process faces the following main technical challenges: The superconducting magnets are heavy and require separation on a stable platform. Traditional methods use cranes and simple support frames for manual assembly and separation of the half-rings. This process not only poses safety risks but is also extremely difficult in terms of adjusting the half-rings' attitude in mid-air and achieving micron-level precision alignment in the radial and axial directions. It heavily relies on the operator's experience and feel, resulting in low efficiency and unreliable accuracy. Furthermore, the assembly process is unstable and prone to stress and damage.

[0025] As shown in Figure 1 and Figure 2 As shown, to solve the above-mentioned technical problems, this application provides a superconducting magnet assembly trolley, including a carrier component and a magnet support component, wherein the carrier component is movably disposed. The magnet support component is disposed on the carrier component and includes a first locking member 9 and a pair of carrier components. Each carrier component is used to connect a pair of superconducting magnet semi-rings 12 of a detachable superconducting magnet, and each carrier component can move relative to the carrier component to move closer to or further away from each other, enabling the superconducting magnet to separate into a pair of superconducting magnet semi-rings 12 or to come together. When the superconducting magnet is separated, the connection between the first locking member 9 and the carrier component is released, and the carrier components are separated by a driving member, thereby separating the superconducting magnet into a pair of superconducting magnet semi-rings. After the pair of superconducting magnet semi-rings 12 come together, the first locking member 9 is connected to each carrier component to lock the position of each carrier component, and at least one carrier component and the first locking member 9 are detachably connected.

[0026] In these embodiments, the supporting component is a movable chassis structure with multiple casters with brakes at the bottom, which can move smoothly and has a positioning and locking function to ensure the overall structural stability during operation.

[0027] The magnet support assembly includes a pair of carriers and a first locking member 9. Each carrier is used to detachably connect to a superconducting magnet half-ring 12. For example, the carrier adopts a high-rigidity aluminum alloy frame structure, and the upper surface is provided with positioning pin holes and quick-release clamping interfaces that match the base of the superconducting magnet half-ring 12, so as to achieve quick and non-destructive clamping.

[0028] Both carrier components are mounted on the support assembly via slide rails, allowing them to move independently relative to the support assembly in the horizontal plane along the direction of their connection (i.e., radially), thus enabling them to move closer or further apart. During the closing operation, the operator or drive device controls the two carrier components to move synchronously towards the center, causing the mating ends of the two superconducting magnet semi-rings 12 to gradually approach and complete the docking. Conversely, the separation operation of the superconducting magnets is achieved by moving them away from each other.

[0029] Once the two superconducting magnet semi-rings 12 are fully closed and aligned, the first locking member 9 is installed in place. This first locking member 9 is a transverse rigid connector, with both ends connected to the flange interfaces on the carrier component via bolts. At least one end employs a detachable connection structure (such as a quick-change pin, connecting bolt 4, or wing nut) to facilitate subsequent disassembly and transport.

[0030] It should be emphasized that, before assembly, the superconducting magnet half-ring 12, which is in the closed state, can also be smoothly separated using this application, reducing separation stress damage.

[0031] Through the above structure, the present invention achieves rigid support, controllable movement and position locking of the superconducting magnet semi-ring 12 during the entire process of closing, separating, aligning and transporting, which significantly improves the safety of operation, repeatability of positioning accuracy and operation efficiency, and avoids the shaking, stress concentration and human error caused by traditional hoisting methods.

[0032] For example, in this embodiment, the first locking member 9 consists of a left section, a right section, and a middle connecting pin. The left section is fixedly connected to the carrier component, and the right section is connected to the left section via a quick-connect pin, but the right section is not directly fixed to the carrier component. After closing, inserting the quick-connect pin completes the overall rigid locking. During disassembly, simply pulling out the quick-connect pin separates the components into two carrier components, thereby dividing the superconducting magnets connected to the carrier components into a pair of superconducting magnet semi-rings 12.

[0033] For example, a six-degree-of-freedom fine-tuning platform (such as a piezoelectric ceramic actuator or a manual fine-tuning screw) is integrated below the slide rail of the carrier component, which can make fine adjustments to the superconducting magnet half ring 12 in the axial, radial and angular directions during the final stage of closing, to compensate for manufacturing or assembly errors.

[0034] In some embodiments, the carrier assembly includes a reference member 6 having a reference surface 15, and each carrier component is mounted on the reference surface 15 in a manner that allows it to approach or move away from each other.

[0035] In these embodiments, the reference element 6 is made from a single machined platform, with its upper surface precision ground to form a highly flat and stable reference surface 15. This reference surface 15 serves as the mounting and alignment reference for the entire magnet support assembly, ensuring that all movements and positioning are based on the same physical reference and avoiding cumulative errors.

[0036] For example, each carrier component has a slider at its bottom, which slides in engagement with a linear guide rail 7 fixed on the reference surface 15. There are two sets of linear guide rails 7, which are parallel and collinear to each other, so that the two carrier components can only move in a straight line along the set closing direction (i.e., radial direction), effectively constraining unnecessary degrees of freedom and improving the guiding accuracy and repeatability of the closing process.

[0037] By directly mounting the carrier components onto the high-precision reference surface 15, not only is the structural hierarchy simplified, but the overall geometric stability and alignment reliability of the system are also significantly improved. During the closing process of the superconducting magnet semi-ring 12, the positional relationship of its mating surfaces is always referenced to the same reference surface 15, thereby ensuring the realization of micron-level mating accuracy.

[0038] In some embodiments, the support assembly further includes a first adjusting member 17, which is connected to the reference member 6. The first adjusting member 17 is used to adjust the deflection of the reference member 6 so that the flange of the closed superconducting magnet semi-ring 12 is parallel and fitted to the vacuum tube flange.

[0039] Based on the aforementioned embodiments, by operating the first adjusting member 17, the reference member 6 can be slightly deflected, such as by horizontal swinging, thereby causing the two carrier members mounted on it and the closed superconducting magnet to tilt synchronously as a whole. This tilting action is used to compensate for the angular deviation between the end flange plane of the superconducting magnet semi-ring 12 and the accelerator vacuum pipe flange after the semi-ring 12 is closed.

[0040] During actual assembly, the parallelism between the magnet flange and the vacuum tube flange is monitored in real time using a laser collimator or electronic level. When a misalignment is detected, the control system or operator slightly adjusts the first adjusting component 17 until the two flange surfaces are parallel and in contact. Only then is the final bolt tightening performed. This effectively avoids stress deformation introduced by forced assembly, prevents stress changes from affecting the electromagnetic performance of the superconducting magnet, and ensures precise alignment between the magnet and the vacuum tube flange.

[0041] In some embodiments, the support assembly includes at least two support frames connected in sequence to form an installation platform 16, and the connection between at least one adjacent support frame is detachable. The first adjustment member is disposed on the installation platform 16.

[0042] Each support frame is provided with at least one of the aforementioned movable parts 3, so that each support frame can move independently when the detachable connection is disconnected; and / or, the mounting platform 16 can move as a whole.

[0043] In this embodiment, the support assembly adopts a modular design. Each support frame is arranged sequentially along the radial direction of the superconducting magnet and is interconnected by a detachable connection mechanism to form an integral installation platform 16.

[0044] For example, in this application, there are two support frames, namely the first support frame 1 and the second support frame 2. The first support frame 1 and the second support frame 2 are detachably connected by connecting bolts 4.

[0045] For example, the detachable connection mechanism includes flange mating surfaces, locating pin holes, and quick-release bolt assemblies located at the ends of adjacent support frames. When the quick-release bolt assemblies are tightened, the two support frames are rigidly connected, forming a stable and continuous installation platform 16. When the bolts are removed and the locating pins are pulled out, the connection is released, and each support frame can be separated from the other.

[0046] The first adjusting component 17 is installed on the upper surface or internal support structure of the mounting platform 16, specifically located below the reference component 6. Since the reference component 6 is fixed to the mounting platform 16, the first adjusting component 17 can work normally to adjust the posture of the reference component 6, regardless of whether the support frame is connected or not, as long as the mounting platform 16 is in the assembled state.

[0047] In addition, each support frame has at least one movable element 3 at its bottom. For example, the movable element 3 can be a swivel caster with brakes, a track-mounted wheel set, or a hydraulically self-propelled drive wheel. Its arrangement satisfies the following two operating modes: Overall movement mode: When all the support frames are rigidly connected to the installation platform 16 through the detachable connection mechanism, all moving parts 3 move synchronously, so that the entire support assembly moves smoothly along the accelerator tunnel track or the ground as a whole.

[0048] Independent movement mode: When the detachable connection is removed, each carrier can be independently controlled by its own moving part 3, which is convenient for segmented transfer, misalignment avoidance or repositioning in narrow spaces (such as bends, equipment rooms).

[0049] In the actual operation process, the operator first moves the installation platform 16 to the vicinity of the magnet installation position, places the complete superconducting magnet on the carrier, and then separates the carrier into a pair of superconducting magnet half-rings 12. Next, the support frame is separated, and the superconducting magnet half-rings 12 are transferred to both sides of the installation flange using the support frame. The support frames are then merged to form the installation platform 16. Afterwards, the carrier is moved to bring the superconducting magnet half-rings 12 together, aligning them with the vacuum flange and completing the final docking installation. After the operation is completed, the connection between the carrier and the superconducting magnet is released, and the support frame is removed separately, greatly improving the efficiency of assembling large superconducting equipment.

[0050] In some embodiments, the support assembly further includes at least two second adjustment members 5, each support frame is provided with at least one second adjustment member 5, each second adjustment member 5 is capable of adjusting the height of the corresponding support frame, and is also capable of adjusting the levelness of the reference surface 15.

[0051] Based on the foregoing embodiments, in this embodiment, the supporting component further includes at least two second adjusting members 5.

[0052] Each support frame is equipped with at least one second adjusting member 5. In a preferred embodiment, each support frame is equipped with two second adjusting members 5, located at its front and rear bottoms respectively, forming a four-point support system suitable for two-section support frames. The second adjusting member 5 is a high-precision mechanical or electromechanical lifting mechanism, such as a manual fine-tuning screw, an electric push rod, or a hydraulic / pneumatic fine-tuning cylinder.

[0053] The upper end of each second adjusting component 5 is rigidly connected to the base of the corresponding support frame, and the lower end is supported on the ground or rail foundation. By independently adjusting the extension length of any second adjusting component 5, the following dual functions can be achieved: If there is local settlement or unevenness in the foundation during the initial stage of equipment arrival, the tops of all support frames can be adjusted to the same design elevation by adjusting each of the second adjustment components 5, so as to avoid the twisting of the installation platform 16 due to uneven support.

[0054] Since the reference component 6 is fixedly installed on the installation platform 16, which is composed of support frames, the overall flatness and levelness of the reference surface 15 are corrected when the heights of each support frame are precisely coordinated. For example, by monitoring the reference surface 15 with a laser level, the control system or operator can simultaneously fine-tune the four second adjustment components 5 to control the levelness error of the reference surface 15 in the X and Y directions within the set range.

[0055] In some embodiments, there are multiple first adjusting members 17, and each of the support frames is provided with at least one first adjusting member 17. Each first adjusting member 17 includes a pair of clamping portions, and a clamping area for accommodating the reference member 6 is formed between the pair of clamping portions. The pair of clamping portions are arranged in a manner that allows them to approach or move away from each other, so that each clamping portion can abut and limit the corresponding side of the reference member 6. By adjusting the position of the clamping portion of each first adjusting member 17, the reference member 6 is driven to deflect, and the deflection direction of the reference member 6 is parallel to the reference surface 15.

[0056] Based on the aforementioned embodiments, this embodiment optimizes the structure and arrangement of the first adjusting member 17. The number of the first adjusting member 17 is multiple, preferably an even number, such as 2, 4 or 6, and each support frame is provided with one of them.

[0057] Each first adjusting member 17 includes a pair of clamping parts. The pair of clamping parts are symmetrically arranged along the length direction (i.e., transverse) perpendicular to the reference member 6 and are mounted on the upper support frame of the corresponding carrier frame by guide rails or screw-nut pairs, so that the two can move closer or further away from each other.

[0058] A clamping area is formed between a pair of clamping parts, and the side of the reference part 6 (or the positioning edge with a flange) is precisely accommodated in the clamping area. When the clamping part moves towards the center, its inner side surface abuts against the left and right sides of the reference part 6 respectively and applies a preload, thereby achieving lateral limiting and rigid clamping of the reference part 6.

[0059] More importantly, the position of the clamping part of each first adjusting member 17 can be independently fine-tuned. For example, by driving a precision lead screw with a servo motor to control the left clamping part to move forward while the right clamping part moves backward, the reference member 6 will be subjected to a lateral eccentric torque, resulting in a slight deflection. If multiple first adjusting members 17 are distributed along the length of the reference member 6 and the clamping displacement of each clamping point is adjusted according to a specific gradient, the overall spatial attitude of the reference member 6 can be precisely controlled.

[0060] In some embodiments, the reference member 6 includes multiple connecting segments, each of the support frames is provided with one of the connecting segments, and in adjacent connecting segments, one of the connecting segments includes a plug-in portion, and the other connecting segment includes a plug-in mating portion, wherein the plug-in portion and the plug-in mating portion are plugged in and positioned together.

[0061] Based on the above embodiments, this embodiment designs the reference component 6 in segments to further improve its geometric reproduction accuracy during the split transportation and on-site reassembly process.

[0062] The reference component 6 includes multiple connecting segments, the number of which matches the number of support frames; for example, two support frames correspond to two connecting segments. Each connecting segment is fixedly installed on the upper surface of its corresponding support frame and rigidly connected by screws or pins to ensure no relative displacement within a single support frame.

[0063] A precision insertion positioning structure is provided at the mating end faces of two adjacent connecting segments: One of the connecting segments has a plug-in portion at one end, which is a protruding cylindrical or dovetail-shaped locating pin. The corresponding end of the other connecting segment has a plug-in mating portion, which is a countersunk hole or groove that matches the shape of the plug-in portion, and a small interference or transition fit clearance is reserved.

[0064] After the two support frames are initially aligned via the detachable connection mechanism, the operator pushes the two connecting sections closer together, allowing the insertion part to automatically enter the mating part. Due to the high geometric accuracy and guide cone angle of the mating surface, such as a 5° chamfer at the entrance, even with millimeter-level initial alignment deviations, it can self-align during insertion, ultimately achieving sub-micron-level repeatability positioning accuracy.

[0065] After connection, all connecting segments together form a continuous, coplanar reference plane 15. Laser interferometer testing showed that the step height difference at the splicing seam and the overall flatness met the alignment reference requirements for the superconducting magnet assembly.

[0066] In some embodiments, the second adjusting member 5 is a lifting support leg, which includes a fixed end and a telescopic end. The fixed end is disposed on the support frame, and the telescopic end can extend or retract relative to the fixed end to abut or detach from the ground.

[0067] Based on the aforementioned embodiments, in this embodiment, the second adjusting member 5 is specifically implemented as a lifting support leg.

[0068] Each lifting outrigger includes a fixed end and a telescopic end. The fixed end is rigidly installed on the bottom frame of the corresponding support frame by bolts or welding; the telescopic end is connected to the fixed end in a telescopic manner and can move relative to it in the vertical direction.

[0069] The lifting legs can adopt any of the following common high-precision structural forms: The manual lifting outrigger consists of an external threaded sleeve and an internal threaded rod. Rotating the handwheel drives the telescopic end to rise and fall.

[0070] The electric lifting outriggers have built-in miniature servo motors and ball screws, and the height can be adjusted via a control panel or remote control.

[0071] Hydraulic / pneumatic lifting outriggers achieve stepless lifting by controlling the oil / air circuit via a manual pump or solenoid valve, and are equipped with a mechanical locking mechanism to prevent retraction.

[0072] All the telescopic ends of the lifting outriggers are retracted to their highest position, lifting them off the ground. At this point, the weight of the equipment is entirely supported by the movement of the bottom of each support frame (such as casters or track wheels), facilitating overall or separate movement.

[0073] In some embodiments, the carrier includes a support base 10, a lower top 14, and a side top 13. The support base 10 is detachably connected to the lug 11 of the superconducting magnet half-ring 12. The side top 13 and the lower top 14 are both disposed on the support base 10. The side top 13 is used to abut against and support the side of the superconducting magnet half-ring 12, and the lower top 14 is used to abut against and support the bottom of the superconducting magnet half-ring 12.

[0074] Based on any of the foregoing embodiments, this embodiment refines the specific structure of the carrier component. Each carrier component includes a support base 10, a lower top 14, and a side top 13.

[0075] The bearing seat 10 serves as the main support frame, with a standard interface on its upper surface for connection to the superconducting magnet semi-ring 12. The lifting lugs 11 are typically pre-installed by the magnet manufacturer at designated positions on the semi-ring housing, enabling quick, non-destructive, and detachable connection via quick-release pins, wing bolts, or hydraulic clamps, facilitating clamping and release.

[0076] The lower top 14 and the side top 13 are both fixedly mounted on the support base 10, and are located directly below and to the side of the superconducting magnet semi-ring 12 (usually radially inner or outer, depending on the magnet structure).

[0077] The lower top 14 is an arc-shaped or flat support block used to abut and support the bottom contour of the superconducting magnet semi-ring 12 and bear the main gravity load.

[0078] The top side 13 is a vertically or inclined limiting block used to abut against the side facade of the magnetic half ring to prevent it from swaying or overturning during movement or closing.

[0079] Through three-point constraint, the carrier component achieves stable, slip-free, and low-stress clamping of the superconducting magnet half-ring 12. Especially during the closing process, as the two superconducting magnet half-rings 12 gradually approach each other, the side top 13 can also play a preliminary guiding role, reducing the risk of collision at the docking surface.

[0080] It should be noted that the lifting lug 11 and the support base 10 are connected, and together with the lower top 14 and the side top 13, they jointly support the superconducting magnet semi-ring 12, ensuring that they are combined into a whole and rigidly connected. After the superconducting magnet semi-ring 12 is assembled and installed, the lifting lug 11 and the support base 10 are separated for hoisting via the lifting lug 11. At this time, the lower top 14 and the side top 13 continue to support and fix the superconducting magnet semi-ring 12.

[0081] In some embodiments, the magnet support assembly further includes two drive members 8, with each carrier component connected to a corresponding drive member 8, and each drive member 8 is used to drive the corresponding carrier component to move.
